According to an embodiment, the AP 201 mayprovide the electronic device 101 with wireless communication based onthe Wi-Fi protocol defined in IEEE 802.11.

According to an embodiment, an external electronic device 202 (e.g., anelectronic device 102 of FIG. 1) may refer to the same device as theelectronic device 101 or a different type of device from the electronicdevice 101. FIG. 2 illustrates the external electronic device 202indicating a laptop computer, but the external electronic device 202 mayinclude a portable communication device (e.g., a smartphone), a computerdevice, a portable multimedia device, a portable medical device, acamera, a wearable device, a virtual reality (VR) device, or a homeappliance.

According to an embodiment, the electronic device 101 may refer to adevice used by a user. The electronic device 101 may refer to, forexample, a terminal, a user equipment (UE), a mobile station, asubscriber station, a remote terminal, a wireless terminal, or a userdevice. According to an embodiment, the electronic device 101 mayinclude a processor 120, an antenna module 197, and a Wi-Fi module 290(e.g., at least a part of a communication module 190 of FIG. 1).According to an embodiment, the electronic device 101 may furtherinclude at least one other component other than the components shown inFIG. 2. For example, the electronic device 101 may further include ahousing (not shown) including the processor 120, the antenna module 197,and the Wi-Fi module 290. For another example, the electronic device 101may further include at least one component (e.g., a memory 130) shown inFIG. 1.

According to an embodiment, the antenna module 197 may include at leastone antenna. The at least one antenna may transmit and receive a signalin the same frequency band and the same channel. For another example,the at least one antenna may transmit and receive a signal, at least oneof a frequency band or a channel differs.

According to an embodiment, the Wi-Fi module 290 (or a Wi-Fi chip) maybe electrically connected with the at least one antenna included in theantenna module 197 and may support a Wi-Fi protocol.

According to an embodiment, the processor 120 may be operativelyconnected with the Wi-Fi module 290. The processor 120 may perform theoverall function of the electronic device 101 for providing Wi-Ficommunication and mobile hotspot communication. For example, theprocessor 120 may establish a Wi-Fi link 210 for transmitting andreceiving data with the AP 201 via the Wi-Fi module 290 on a firstchannel of a specified frequency band (e.g., a frequency band having acentral frequency of 2.4 GHz or 5 GHz). For another example, theprocessor 120 may establish a mobile hotspot link 220 with the externalelectronic device 202 via the Wi-Fi module 290. According to anembodiment, the processor 120 may establish the mobile hotspot link 220on the same channel (i.e., the first channel) as the first channel onwhich the Wi-Fi link 210 is established.

FIG. 3 illustrates an operation of a Wi-Fi module 290 including one coreand the Wi-Fi module 290 including a dual core according to variousembodiments.

Referring to FIG. 3, the Wi-Fi module 290 may include a core. The coremay refer to a software or hardware unit which processes data totransmit a signal of at least one frequency band defined in IEEE 802.11.The Wi-Fi module 290 may include a plurality of cores 292 and 294 asshown in reference numeral 301, or may include the one core 292 as shownin reference numeral 302.

As shown in reference numeral 301, when the Wi-Fi module 290 includesthe plurality of cores 292 and 294 according to an embodiment, anelectronic device 101 may perform wireless communication in a pluralityof frequency bands. For example, the electronic device 101 may performWi-Fi communication (e.g., Wi-Fi traffic flow 310) with an AP 201 in afirst frequency band (e.g., 2.4 GHz) via the first core 292 and mayperform mobile hotspot communication (e.g., mobile hotspot traffic flow320) with an external electronic device 202 in a second frequency band(e.g., 5 GHz) via the second core 294.

As shown in reference numeral 302, when the Wi-Fi module 290 include onecore (e.g., the first core 292) according to an embodiment, the cost ofproducing the electronic device 101 may be more reduced than that inmounting the plurality of cores 292 and 294. Furthermore, the Wi-Fimodule 290 may enable the one core 292 to reduce power consumptionrequired to enable the plurality of cores 292 and 294.

According to an embodiment, the electronic device 101 may perform theWi-Fi communication 310 and the mobile hotspot communication 320 bymeans of the one core. When the Wi-Fi communication 310 and the mobilehotspot communication 320 are performed in different frequency bands, adelay may occur while the frequency bands are switched. When the Wi-Ficommunication 310 and the mobile hotspot communication 320 are performedon different channels of the same frequency band, inter-channelinterference may occur. As shown in reference numeral 302, theelectronic device 101 according to an embodiment may perform the Wi-Ficommunication 310 and the mobile hotspot communication 320 in the samefrequency band and the same channel using a time sharing scheme.

According to an embodiment, the frequency band where the Wi-Ficommunication 310 and the mobile hotspot communication 320 are performedmay be 2.4 GHz or 5 GHz. According to IEEE 802.11, because the number ofchannels allocated in the 5 GHz frequency band is greater than thenumber of channels allocated in 2.4 GHz frequency band and because thesignal transmitted and received in the 5 GHz frequency band is less innoise than the signal transmitted and received in the 2.4 GHz frequencyband, the electronic device 101 may perform the Wi-Fi communication 310and the mobile hotspot communication 320 in the 5 GHz frequency band.

According to an embodiment, the 5 GHz frequency band may include achannel limiting the mobile hotspot communication 320. For example, atleast one channel in the 5 GHz frequency band may be an indoor-onlychannel or a dynamic frequency selection (DFS) channel. The indoor-onlychannel may refer to a channel where the mobile hotspot communication302 is permitted only indoors. The DFS channel may refer to a channelused in a radar or an artificial satellite for a public purpose such asnational defense or a weather forecast. The AP 201 may perform Wi-Ficommunication over the DFS channel in only a condition supporting a DFSmaster function. When supporting the DFS master function, the AP 201 mayperiodically or aperiodically monitor a radar signal (or an artificialsatellite signal) on the channel where Wi-Fi communication is performed.When the radar signal (or the artificial satellite signal) is detected,the AP 201 may re-establish a Wi-Fi link on a non-DFS channel with theelectronic device 101. According to an embodiment, the electronic device101 may fail to support the DFS function to ensure a mounting space andprevent power consumption required to detect a radar signal. In thiscase, the electronic device 101 may receive information indicatingwhether a radar signal of the DFS channel is detected from the AP 201 ormay identify the DFS channel by storing information about the DFSchannel in a memory (e.g., a memory 130 of FIG. 1) in advance. Accordingto an embodiment, the DFS channel may differ for each country.

As described above, to use the Wi-Fi communication 310 and the mobilehotspot communication 320 in the 5 GHz frequency band through one core,the electronic device 101 needs to conform to regulation by theindoor-only channel or the DFS channel. In various embodiments describedin FIGS. 4 to 10 below, the electronic device 101 may change a state(e.g., a channel or the intensity of a transmitted signal) of a mobilehotspot link 220 depending on a state of a Wi-Fi link 210 (e.g., whetherit is the indoor-only channel or the DFS channel).

FIG. 4 illustrates an operational flowchart of an electronic device 101for changing a state of a mobile hotspot link 220 depending on a changein state of a Wi-Fi link 210 according to various embodiments.Operations shown in FIG. 4 may be performed by the electronic device 101or a component (e.g., a processor 120) included in the electronic device101.

Referring to FIG. 4, in operation 405 of a method 400, the electronicdevice 101 (e.g., the processor 120) may establish the Wi-Fi link 210 ona first channel with an AP 201.

In operation 410, the electronic device 101 may establish the mobilehotspot link 220 on the first channel with an external electronic device202. According to an embodiment, the electronic device 101 may establishthe mobile hotspot link 220 through a Wi-Fi module 290 including onecore. The electronic device 101 may perform Wi-Fi communication andmobile hotspot communication on the first channel using a time sharingscheme.

In operation 415, the electronic device 101 may detect an eventassociated with a change in state of the Wi-Fi link 210. According to anembodiment, the event associated with the change in the state of theWi-Fi link 210 may refer to when the first channel is a DFS channel. Forexample, the AP 201 may obtain a radar signal or an artificial satellitesignal while performing Wi-Fi communication 310 with the electronicdevice 101. When the AP 201 transmits a first signal to command tochange the channel of the Wi-Fi link 210 from the first channel to asecond channel which is a non-DFS channel to the electronic device 101,the electronic device 101 may identify that the first channel is the DFSchannel. For another example, when the Wi-Fi link 210 between theelectronic device 101 and the AP 201 is disconnected, the electronicdevice 101 may identify that the first channel is the DFS channel bymeans of information previously stored in a memory 130. According toanother embodiment, the event associated with the change in the state ofthe Wi-Fi link 210 may refer to when the first channel is an indoor-onlychannel. For example, the electronic device 101 may receive informationindicating that the first channel is the indoor-only channel from the AP201 or may identify that the first channel is the indoor-only channel bymeans of information previously stored in the memory of the electronicdevice 101.

In operation 420, the electronic device 101 may change a state of themobile hotspot link 220 based at least on the detected state of theWi-Fi link 210. According to an embodiment, the state of the mobilehotspot link 220 may refer to a channel. For example, the electronicdevice 101 may detect that the first channel of the Wi-Fi link 210 isthe DFS channel and may change the channel of the mobile hotspot link220 from the first channel to the second channel in response to changingfrom the first channel to the second channel which is the non-DFSchannel.
